doesSasPidScaleKp

Determines if the SAS scales Kp according to the scaling information in this object or not. Set this to match the reality in the SAS you are studying. For example: AIM "PIDcon": does not scale KP and TI AIM "PIDx" : DOES scale KP and TI

Declaration

public bool doesSasPidScaleKp
